SANITARY CLOSET.

Application filed July 27, 1921. Serial- No. 487,917.

ject of the King of Great Britain, residing at Bin-wood, near Sydney, inthe State of New South Vales, Commonwealth of Australia, have inventedcertain new and useful.

Improvements in Sanitary Closets, of which the following is aspeclfieation.

This invention relates to improvements in sanitary closets of the classin which a chemical solution is employed to dissolve the fiscal matterand render the contents in-- nocuous.

In such closets heretofore ditliculty has been experienced indisintegrating the faeces so that the solution .inay act quicklythereon. A further difficulty has been the removal of the paper andother insoluble material. In the present invention the faecal matter inthe closet pan is forced or compressed through a fixed grating whichprevents the paper and other comparative ly large insoluble materialfrom passing thcrethrough, which material is scraped from the gratingand deposited in a removable receptacle within the casing. The closet isprovided with a hinged seat, the n'iovement of which controls andoperates a double armed lever, one arm being weighted and the othercoupled by a downwardly ere tending link or rod to an arm on acompressor pivotally mounted on a shaft or stud. The compressor plate isadapted to lie flat against the grating and force the fa-:calmattertherethrongh in a line state of division and on a second arm on saidcompressor is pivoted the scraper. ()n the com pressor shaft is alsomounted a bowor cam lever movable w1th said compressor and adapted tocontact with a projection depending from a slidable or pivoted partitionwhich normally seals the casing. When' the seat is lowered to be usedthe compressor is forced upwardly to a vertical position andsimultaneously the cam lever moves back or withdraws the partition. Atthe same time the scraper passes over the surface of the grating andremoves the paper and insoluble material therefrom and deposits it inthe crate or receptacle. The movement of the scraper is obtained bycausing it to contact and ride on the convex face of a curved block ortoppling guide pivoted on a stud in the casing and supported on anotherstud. The rearward motion of the arm on which said scraper is pivotedcauses the rearward end of the scraper to rise on the curved block andthe forward end to make a parallel movement over the surface of thegratu'lg. On reachmgthe end of the curved block and there now being apreponderance on that side, the scraper end is carried clear of thegrating and the rear end caught by a fixed stop.

On the seat being thrown back, the StilitIJfil', compressor, andslidable or pivoted iiartition are returned to their normal positions,the scraper in its passage ren'ioving any matter which may havecollected on the side of the casing while the compressor presseson thegrating to force the matter,

except the paper and the like, through the openings therein. The wholeof the apparatus is enclosed in a suitable casing and is tilled to justabove the level of the compressor plate with a suitable solution fordissolving the faecal matter. In the bottom of said casing I provide aspace which is filled with charcoal or other suitable material and anoverflow pipeis connected to said space whereby any excess solution inthe upper conniartinent may overflow and run into the lower chamber. Incase the closet is used as a urinal only, I provide a lever and footattachment which connects and'moves the we1ghted double armed leverunder the seat, which action causes the slidable or pivoted partition toopen, when the closet may be used for urinal purposes.

I will, however, now refer to the aeconr panying drawings in order thatthe invention may be more clearly comprehended.

Figure 1 is a plan of the complete closet.

Figure 2 is a longitudinal section on the line A.A, Figure 1, showingthe closet in the open posit-ion.

Figure 3 is a fragmentary perspective view of the foot operating levers.

Figure l is a similar view to Figure 2 showing the closet in the closedposition,

' while a counter weight 11. 12 is the main spindle connected to theseat lever 13 by connecting to limit the travel oi the curved extension.

18. is a cam lever connected to the pivot 19 which lever operates thesealing slide 26 bypushing against the extension piece 27 otthe slide.This slide-26, when in the closed position, takes into a recess'28 inthe casing. 29 is the grating on which the compressor comes to rest andis a crate to receive paper or other insoluble matter scraped oil thegrate by the scraper '17. 2,1 is the overflow pipe leading from theseparating chamber into the charcoal chamber from which the liquid isdrawn oft by pipe 3-1- is a door provided in the casing for ren'iovingthe paper crate and for cleaning purposes. is a 'root lever pivoted at36 and terminating in a U shaped piece 35 This foot lever is actuatedwhen the closet is to be used as a urinal. 37 is a double armed leverpivoted to the casing at one end of which [its into the U piece 35 andthe other end is slidably and loosely connected to the slide 26, as at37 In operation, the act of manually pulling down the pivoted seat 9against its counterbalance weight 11 causes the connecting rod 1% tomove downwardly thereby raising the compressor 15 oii' the grate 29 tobring same 'to aboutthe vertical position as shown in Figure 2 and inenlarged view, Fig. 5. The curved extension lever 18 is lifted by thepin 20 riding over toppling guide 21 which acts as a cam and causes thescraper '17 to move across the grate 29 as shown in the midway positionin Figure 5, until the pin 20 moves right across the guide 21 and dropsover same. The preponderance of weight or the lever 18 then causes thescraper 17 to move upwardly on its pivot 19 to the position shown inFigure 2. The lever v25 meanwhile pushes against the extension 2'?thereby opening the sealing slide'26. The compression of the :tzeca'lmatter through the grating is atl'ected on removal of the weight of theperson from the seat 9 which rising, causes the connecting rod 1-1 tomove upwardly. At the end of this movement the compressor 15 comes torest on the grate 29 and forces the 'trecal matter therethrough,breaking it up, and allowing the liquid to act thereon. The paper andother insoluble material left on the top otthe grate is moved by thescraper 17 into the crate 30 when the seat is again lowered by hand. Thesolution in the pan is keptup to a level the discharge pipe 33.

which just covers the compressor and grate, the overflow being carriedaway by pipe 31 to the charcoal chamber 32 and thence by Normally theslide 26 is closed by the lever 37 through the action of a spring 37 Iclaim:
